1.1 These test methods cover the measurement of moisture content, ash content, and organic matter in peats and other organic soils, such as organic clays, silts, and mucks.

1.1.1 Method A – moisture is determined by drying peat or organic sample at 105 °C.

1.1.2 Method B – Alternative moisture method which removes the total moisture in two steps: (1) evaporation of moisture at room temperature, (2) subsequent oven drying of air dried sample at 105 °C.

1.1.3 Method C – Ash content of a peat or organic soil sample is determined by igniting oven dried sample from moisture content determination in a muffle furnace at 440 °C.

1.1.4 Method D – Ash content of a peat or organic soil sample is determined by igniting oven dried sample from moisture content determination in a muffle furnace at 750 °C.

1.2 This test method should be used for geotechnical and general classification. In addition, the test method should be used when peats are being evaluated for use as a fuel.

1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. Use Practice D 6026 for determining significant digits to report.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This standard is referenced in the 2012 International Green Construction Code™.
